Mikaela Shiffrin reacts after qualifying for the second run in giant slalom on Lower Ruthie's Run at the Nature Valley Aspen Winternational Audi FIS Ski World Cup at Aspen Mountain in Aspen on Saturday, Nov. 24, 2012. Shiffrin, 17, lives and trains in Vail.

ASPEN — Vail’s Lindsey Vonn and Eagle-Vail’s Mikaela Shiffrin did very well in the first run of Saturday’s World Cup giant slalom here.

Having lost some cardiovascular fitness this month because of an intestinal illness that put her in the hospital for two nights, Vonn still finished 10th in the first run. Shiffrin was 18th in just her seventh World Cup GS start, qualifying her for the second run for the second time in that discipline.

“I thought I skied really well,” Vonn said. “I came out attacking, especially the top and the flats. There was a compression delay on the bottom and I just stumped out — my legs just gave out on me. I used pretty much every last ounce of energy to pull out of that mistake, and the last 10 gates or so I just struggled to make it down and lost quite a bit of time.
